Roger Federer aced Andy Roddick 50 times in the finals of Wimbledon last week, and Roddick returned the favor 27 times at speeds up to 140 miles an hour.
There are good college tennis players and teaching pros in Memphis who can consistently hit a 120-mile-an-hour serve. Or hit a racquetball 150 miles an hour. Or put so much slice on a serve in ping pong that points are over in a few seconds.
This is what happens when players who are already bigger, stronger, and more skilled get the benefits of better equipment too.
